When processing an XML file directly with ConTeXt, i.e. using \startxmlsetups rules, how can I make use of the MathML module for the MathML content in my XML source? Should I include a specific piece of code with a \registerctxluafile command as well as / instead of \usemodule[mathml]? Do I need to use something other than \xmlflush to pass the XML to the module?

Sorry, it's probably obvious but I can't work it out!

Thanks.
